The specimen is in flow^er and presents immature leaves, which are 

 glabrous and considerably smaller than are those on our Chinese material. 

 The tree is manifestly deciduous, the new leaves appearing with the flowers. 

 I can see no reason, in the absence of more complete material, and especially 

 mature leaves and fruits, for distinguishing this Philippine form from this 

 well-known Chinese and Japanese species. In floral characters it conforms 

 very closely with material from southern China.

A shrub about 1 m high, the branchlets, petioles, and pedicels 

 rather densely appressed-paleaceous with oblong, obtuse to acu- 

 minate, 0.5 to 1.2 mm long, thick scales, with similar ones on 

 the midrib and nerves on both surfaces of the leaves. Leaves 

 oblong, chartaceous, 5 to 8 cm long, 2 to 3.5 cm wide, the upper 

 surface brownish-olivaceous, shining, the lower paler, here also 

 with scales on the reticulations, the apex shortly acuminate, 

 base acute to obtuse, margins denticulate-setose; lateral nerves 

 5 or 6 on each side of the midrib, prominent, the reticulations 

 distinct; petioles 0.5 to 1 cm long. Flowers axillary, solitary, 

 white, ebracteate, about 2 cm in diameter, their pedicels 5 to 8 

 mm long. Sepals ovate-elliptic, about 8 mm long, the outer two
